Appiieauon fiied'oetober 14, 191e. f serial Narieasee;

To all whom t 'may concern: y f Be it known that Ij, FRELING C.' FOSTER,

Junior, a citizen of the United States, residey ing at Chicago, in' the county ofV Cook and" State of Illinois, have inventedla certain new and useful Improvement in jPerfume-Dis-f persers, of which the following is a specilication.

My invention relates to aI perfume dis-tk perser, and I have illustrated it in connection with` an automobile, though of course it could be used in any'other position. One

forin of the invention Vis illustrated in the accompanying drawings, wherein- Figure l is a side view of a portion of anV automobile showingV my devicein position;

on the mud guard;

Fig. 2 is" av longitudinal section through the disperser; r Fig. 8 is a rearfelevation;

Like parts are indicatedbysimilar letters in all the figures.

A is an automobile wheel.y

B, B, thel mudrguard, to which the dis-lv pei-ser is secured by means ofthefscrew bolt- C, nut G1, and shouldery C2.

D is a frame annular in shape.

E is a cup-like structure closedv by the end F, but open at G. It? i'slheldin position by ribs H, H, which areconnected tothey cup and the inside of the rim-shaped fra-nie.

The cup E is provided with a hole J, andis iilled or lined with any desired material, as, for example, an absorbent lining K. It is provided with a perforated closure L, and a perforate cap M. Between the closure and the cap is located a small fan N, and within the annular frame is a large fan O. These two fans are mounted on the shaft P. This shaft is shouldered at Q, R, to prevent its motion toward the right, and the hub S of the fan N bears against the closure L to prevent its motion toward theleft.

I wish my drawings to betalren as diagrammatic although it does present an operative structure. I do not wish to be limited to the precise form, arrangement, structure and shape of the several devices or parts which I have shown.

The use and operation of my invention are as follows It will be understood that my invention broadly speaking consists in means for dispersing perfumes by the action of a current in itsy scope to al of air, and it particularly comprises means wherein one fan driven apparatus furnishes the motor power'to drive another, which inv turn propels the current of perfumed air in the: desired direction.l The disperser could belpl'aced inf any desired position(r I have suggested its being'placed atthe farther end ofianlA automobile, and? for convenience, of placingit on the'mud guard. vThat is,'when thetautomobile is 'ini motion the motor fan will be vdriven by the' current of air and the dispersing fan will 'be driven bylits connection from the motor fan. The air will ybe drawn in through the hole in the top of the cup, and will he charged with perfume, and then by thedistributingr fan such perfumed air will be dischargedland distributed toward the rear.y v

The cup constitutes y a mixing device whereby the air and perfume are mixed. The large fan is a motor which operates the mixer and also the distributer. The small fan is the'distributer, which,by moving the current of air, causes the mixer to operate andy also tovmix air to be distributed. In my kpreferred;form my device is adapted 4to beused for theimpregnating of air with perfume, bu'tl'it'is obviousthat the device? wouldk beoperatedl for other purposes, and that it must not and cannot be limited mere perfumey disseminator. The device is really a vaporizer adapted to vaporize any liquid and mix it with the air, and then diifuse it or discharge it.

Attention is called in this connection to the fact that certain liquids are difficult to vaporize, but that they vaporize much easier under low absolute pressure conditions. That is to say, they vaporize at a pressure less than atmospheric much more easily than they vaporize at atmospheric pressure, and my device is so arranged to provide a minus pressure in the mixing chamber, which minus pressure will assist in the vaporizing of the liquid. Reference to the drawings will show that the pump fan is operated to draw air out of the mixing chamber through the perforated partition, but that air is allowed to enter the chamber only through the single small opening in the wall thereof. This small Opening is much smaller than the effective opening of the passages through the partition through which the air is discharged, so that when the fan is operated,

10fty the air Will be sucked out more rapidly than it can at atmospheric pressure enter through the hole. rlhe result will be a minus pressure` in the mixing chamber, greater, that is to say, more and more below atmospheric pressure as the speed of the fan increases. Thus it the perfume or medicine or other liquid wished to be vaporized is hard to Vaporize, the speed of the fan will be increased, the minus pressure increased, and the yan porization will go on in the usual Way.

l claim:

l. ln a perfume distributer the combination of a motor fan With a distributer fan connected therewith and driven thereby, and an air and perfume mixer between thein.

2. ln a perfume distributer the combina tion ci a motor fan with a distributer fan connected therewith and driven thereby and an air and perfume miner between them provided with an air inlet and an air outlet in the mouth of which is situated the distributer ian. y

3. A. vaporiaer comprising a cylinder substantially closed at one end and on the sides and open at the other end, a liquid supply source contained Within the cylinder, a pen forated partition in the cylinder between its open end and its closed end, the liquid supply source being located between the partition and the closed end oli' the cylinder, an air intalre passage inthe Wall of the cylinder connnunicating with the part of the cylinder containing the source of liquid supply,` a pertorate Wall closing the open end ot the cylinder, a suction fan located Within the open end ot the cylinder outside of the apertured partition Wall, and means for rotating the fan to draw air out or" the chamber, the eectiye area of the per'orations in Copies o this patent may te obtained :for

nassaui the partition Wall being greater than the area of the intake passage.

l. A. vaporizer comprising a mixing chamber, a motor fan mounted for rotation upon an aXis passing through the mixing chamber, a shaft carrying said fan, a suction tan carried by the shaft, the vanes of the motor fan extending outwardly beyond the mixing chamber, a source of liquid supply within the chamber, a suction fan mounted upon the motor tan shaft and adapted to be driven thereby, and discharge passages leading from the chamber to the fan, an intake passage discharging into the chamber, the respective area of the passage leading from the chamber Ato the fan being greater than the area oi` theinta-ke passage.v

5. A vaporizer comprising an annular frame,a mixing chamber, radial arms adapted to support it in a central position on one side of the trame, a motor `tan rotatably mounted Withinthe frame, having the etec4 tire ends ot its yanes extending outwardly beyond the mixing chamber, the chamber being open on one side, a perforate Wall closing such open side, a liquid distributing' member Within the chamber, a suction fan in the open side of the chamber, a driving connection between it and the motor Jian, an air inlet passage in the Wall of the chamber having its effective area smaller than the eliective area of the opening in the perforated partition.

ln testimony whereof, l affix my signature inthe presence of twov Witnesses this 10th day of xOctober 1916.
